I'd like to second Liv and say that all over Mexico, people eat field corn fresh.
Having grown up in Iowa--granddaughter of a farmer, I was VERY skeptical at first. But it is actually much tastier--not "sweet" but has a much fuller flavor. Now when I return to the midwest of the USA and eat sweet corn I find it just that--sweet, and lacking other flavor.
Of course, we are making tortillas, pozole, and tamales so the vast majority of the corn is left to fully mature, but stalks with two or three ears, have one or two removed to eat as fresh corn to allow the other ear to get all the nutrients from the plant.
